fix github CI tests on windows

[ahornby]

Summary:

These were failing on github

• Fix use of regex in test in FsUtilTest.cpp
• MSVC exception_ptrs are not comparable, was breaking ExceptionTest
• Fix lookup of executable path on windows, which was breaking SSL test

Test Plan:

python build/fbcode_builder/getdeps.py build --src-dir=. folly
python build/fbcode_builder/getdeps.py test folly

before, broken:
